LIFE-BOAT.

Application filed. June 15, 1915, Serial No. 34,177. Renewed February 9, 1917.

To all whom it may concern:

Be it known that I, Miorrar. ZARADZKI, a subject of the Czar of Russia, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Life-Boats, of which the following is a specification.

This invention relates to certain new and useful improvements in life boats.

An object of the present invention is to provide a life boat that may be readily carried by a ship and one which will occupy a minimum of space in storage on a ship.

A further object of the invention is to provide a life boat including a carrier portion for persons and a conning tower to enable the occupants to sight other vessels.

A still further object of the invention is to provide a life boat with an air tight compartment at the lower end thereof with the stabilizing weight placed therein to cause the same to assume a normally upright position, the air tight compartment acting to hold the life boat on the surface of the water should the same capsize.

A still further object of the invention is to provide a life boat including an inclosing housing with stabilizing wings or floats hinged to the outer opposite Walls thereof and operable from the interior of the boat to cause the same to rise from their normal position adjacent the outer sides to a horizontal position for holding the boat in upright position on the surface of the water.

VJith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrange ment of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views Figure 1 is a top plan view of the boat partially broken away showing the hinge connection of the stabilizing floats at one side of the boat.

Fig. 2 is a vertical cross sectional view of the same illustrating the mechanism operated from the inside of the boat for raising to horizontal position the stabilizing floats, and

anism for moving to operative position the stabilizing floats.

Briefly described, the present invention aims to provide a life boat that is extremely simple in construction, inexpensive to manufacture, one that will occupy a minimum of space in position on a carrying vessel, and a life boat which will at all times float upon the surface of the water. The boat is preferably built of the coneshape shown with an air tight compartment and stabilizing weight at the lower end thereof and an occupant compartment adjacent the upper end with a conning tower secured to the upper end of the boat with means positioned on the inside of the boat adjacent the upper end for moving to operative position stabilizing floats hinged to the outer walls thereof.

Referring more in detail to the accompanying drawings, the reference numeral 10 designates the body portion of the boat which is preferably of cone-shape as shown and being constructed of sheet metal or other suitable material. An angular transverse partition 11 divides the boat into upper and lower compartments 12 and 13 respectively, the said partition constituting a seat and foot rest for the occupants. The lower compartment 13 is preferably formed air tight and carries at the lower end thereof a stabilizing weight 14 which will tend to hold the body in a normally upright position.

The body portion 10 of the boat is open at its upper end and receives thereon the flexible covering wall 15 of waterproof material such as heavy canvas and has the peripheral edges thereof turned over the upper edge of the boat 10 as at 16 and secured in position thereon by the lacing cord 17 passing through openings provided in the turned over edge 16 of the cover and openings provided adjacent the upper end of the body portion 10, the ends of the cords terminating inwardly of the boat body as indicated at 18 and secured to hold the cover on the boat.

A conning tower 19 is carried centrally of the cover 15 being formed integral therewith and of the same material, a reinforcing ring or band 20 being positioned at the upper and lower ends thereof and secured in position by clips or eyelets 21 carried by the conning tower 19. Any suitable number of openings 22 of the desired shape may be provided in the side walls of the conning tower 19 and closed by glass plates 23 through wiich the occupant of the boat may sight other vessels.

Means are provided to assist the stabilizing weight ls: to hold the lite boat in normal upright position and includes laterally extending float membersQt formed of cork or other suitable buoyant material, the inner ends of which are coincident to the curvature of the side walls of the boat body 10 and carrying at each inner corner thereof hinge members pivotally connected to radial ears 26 secured to the outer wall of the boat body 10, this construction being clearly shown in Figs. 1 and 3. The lower outer ends of the floats 24 carry eye-bolts 2 7, to which are connected one end of the cords 28, the other end of the cords being connected to. the eyebolts carried by the outer wall of the boat body at a point suit ably spaced below the hinge connections and 26 ot the float. Eye-bolts 30 are secured to the upper outer ends of the floats 24: and have connected thereto one end of the cables Slwhieh pass through openings 32 provided adjacent the upper ends of the boat body 10 tobe received on winding drums 33 positioned inwardly of the boat body. The winding drums are mounted in suitable supporting brackets 3i and each winding drum carries a ratchet wheel to be engaged by a pivoted pawl 36 supported on the winding drum braeket'Z-Bt, a crank handle '37 being provided foroperating the winding drum for elevating the floats 2% to operative horizontal position.

From the-above'detailed description of the invention, it is believed that the construction and operation thereof will be readily understood, it being noted that the buoyant floats 2-1: are normally positioned adjacent the sides of the boat body 10, but which may be'readily moved to operative horizontal position asshown in Fig. 3 by causing the cables- 31 to be wound upon the drums This operation will cause the floats-to raise to horizontal position and be limited in such movement by the lower connecting cords 28. A sul'lic'ient amount of fresh air for the occupants of the boat will enter through the cable openings 32 and the openings for the 5 lacing cord 17 while a person within the boat may readily view from the conning tower the surroundings and give signals for assistance.

While the form of the invention herein 5 shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction with-out do 6 parting from thespirit and scope of the invention as claimed.

What I claim new is l. A life boat, including a cone-shaped body portion, a transverse angular parti- 0.-

tion dividing thesame into an upper 'compartment and an air tight lower compartment, a stabilizing weight mounted in the lower air tight compartment, a cover detachably connected to the upper end of the 7 beat, a conning tower carriedby the cover, floats hinged to the outer wall of the boat, winding drums. supported on the inner walls thereof, cords for raising said. floats to horizontal position securedto said floats and to 7 said drums and cords for limiting the upper movement of the floats. V v

2. A life boat including a body portion divided int-o an upper com 'ia rtment and a lower air tight compartment, a flexible cover 8 including an edge turned over the upper end of the boat, and detachably secured thereto, a conning tower carried by the flexibleco'ver, reinforcing rings for the upper and lower ends of the conning tower and 8 floats hinged to the outer wall of the boat and operable 'interiorly thereof.

3. A life boat including a hull, a detachable cover mounted thereon, floats hinged to the outer wall of the hull, winding drums 9 supported on the inner Wall of the hull, cables connecting the floats to the winding drums .vherebythe same may be moved to horizontal operative positions and means for limiting the upward movement of the floats. 9
